Zinc alloy die casting technology of manufacturing analysis: complex casting zinc alloy die casting is a kind of electromagnetic pump low pressure casting technology as the core, aluminum smelting and molding compound purification technology and new technology with the core of manufacturing, production of high quality zinc alloy die casting the modern technology.Long life and it USES a new lining material has its own insulation system can be used in a large number of continuous production, at the same time for batch production.The technology of molten aluminum purification of high efficiency, long life and low cost effective, easy to install, use, and flexible.Zinc alloy die casting high skills what impact to us?The core manufacturing process modeling can see casting quality and production has a direct impact.Casting porosity, the adhering sand, scar, thermal cracking and surface quality, dimensional accuracy, using sand performance relationship is very good.Modeling and manufacture of

Due to poor casting properties of titanium, titanium melt mold casting way set is particularly important, if by the method of casting co-cr alloy, stainless steel vertical casting way, often without all casting.Titanium investment casting way has the following requirements:Casting diameter to coarse (not less than 4 mm) and short, guarantee the titanium liquid have enough quantity, injection casting cavity through the shortest pathways;Cast moudle and joint should be bold;The number of casting way should be 3 ~ 4 root;Can adopt parallel method, also can use the lateral thrust method;Avoid to form a right Angle.The mold temperature on the properties of titanium castings surface effectsTitanium fluid is polluted by the embedding material, in addition to the vacuum degree and the embedding material with fused cast made room of related components, but also related to the mold temperature.Liquid molding at high temperature, titanium is easy to react with the embedding material, Zr, Al and S

Dry type magnetic separator is one of the indispensable equipment in the mineral processing equipment, is the material of magnetic characteristics of the ore concentrate can choose other production is extremely strong, widely used in particle size 3 mm below the magnetite, pyrrhotite, roasted ore and ilmenite wet magnetic separation of materials, also used in coal, non-metallic mineral, building materials and other materials in addition to iron.Very suitable for arid area.Dry magnetic separation machine in the process of production will meet motor fever phenomenon.Today, gongyi city xin di mining machinery factory, for everyone to introduce the cause of the dry magnetic separation mechanical and electrical machine fever.The cause of the dry magnetic separation mechanical and electrical machine overheating:1. Magnetic bearing parts of the mechanical and electrical machine lubrication condition is bad, the friction heat;2. The motor wiring adverse or switch attachment misconnection or wi

Ball valve is a kind of use a sphere as a closing of the valve, the valve body, valve seat, mainly for the sphere, the valve stem and handle (or other drive).Driven by the valve stem, and around the ball valve axis of rotation.Mainly used in the pipe used for cutting or distribution and the change of flow direction of medium.There are many different kinds of ball valves, including its action principle and medium and application fields of different, today small make up to introduce the relief valve and the working principle of the float valve.The working principle of the float valveAccused of floating ball valve is love by rotary valve to keep the valve open or occlusion.Ball valve switch lightweight, small size, can make it big caliber, reliable sealing and structure?Simple, easy maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, has been widely used in various industries.Remote control float valve is love by rotary valve to keep the

Due to the stainless steel pipe sizes, according to the welding of stainless steel pipe fittings unique place, as far as possible reduce the amount of heat input, the manual electric arc welding, argon arc welding is adopted two kinds of methods, d > Φ 159 mm adopts argon arc welding, manual arc welding surface.D ≦ Φ 159 mm all use argon arc welding.Stainless steel pipe welding technology to meet the conditions.(1) manual arc welding with welding machine adopts dc reverse connection, when using dc argon arc welding is pick up;(2), it should be before welding wire with oxide coating on the surface of the stainless steel wire brush to brush off, with acetone to wash;Electrode should be in 200-250 ℃ drying 1 h, as you take;(3) the workpiece before welding groove on both sides of the 25 mm within the scope of the clean up oil pollution and so on, with acetone to wash groove on both sides of the 25 mm;(4) argon arc welding, the nozzle Φ 2 mm in diameter, extremely rich tungsten tungsten ele

In the process of forging machinery, there are many risk factors will be a lot of people ignored, below is for you to introduce what are the risk factors.Forging is one of the methods of metal pressure processing, it is an important part in mechanical manufacturing.According to the forging processing when the different state of temperature of the metal materials, can be divided into the hot forging, warm forging forging and cold forging.This article refers to the hot forging, the processed metal materials in the red state (forging temperature range), by the impact of the forging equipment on metal or static pressure, the shape of the metal plastic deformation and get expected size and organizational structure of forging.In the forging workshop of main equipment are forging hammer, press, hydraulic press or crank press, furnace, etc.Production workers often in vibration and noise, high temperature burning, smoke, and head, blank pile up bad work environment, therefore, to operate the eq

Magnetic separator should be a lot of people can use, but how many people are there in the daily maintenance of machine will attach importance to it, let's take a look at what is the daily maintenance of magnetic separator.1, clean parts.Cleaning including filling pipe, groove box, and the body surface clean.When cleaning do not use sharp or magnetic objects, myself also don't carry the door CARDS, bank CARDS, mobile phone items, lest cause degaussing and other unnecessary loss.2, lubrication.Each bearing lubricating oil to add and replace, add a general use, replaced every three months, pay attention to the brand lubricants, don't mix.Finally, to deal with the problems and faults in the operation of last time, completes the registration and record.In daily routine check is static management, need do detail, like high magnetic separator a hundreds of thousands of, have the troubleshooting and maintenance will be a waste of time and money, delay the progress.More information on high-str

About everyone knows how much the pneumatic ball valve, the following is to introduce the pneumatic ball valve.Pneumatic ball valve and ball valve has a O V type ball valve.O-type ball valve structure of floating type, ball core for precision casting, hard chromium plating processing, appearance with enhanced ptfe seat material, flow crossing the same as the pipe diameter, flow capacity, little flow resistance, closing without leakage, generally do switch valve is used, especially suitable for high viscosity, v-shaped ball valve fixed structure, ball core open v-shaped incision, which can realize shear fiber, granular media.Process equipment under different choice of pneumatic or electric actuators, forming an and electric ball valves, pneumatic ball valve such as pneumatic ball valve must be regulated to achieve proportional valve positioner, such as the electric ball valve to be regulated to achieve proportional election electronic actuators or servo amplifier, etc.From the material,
