Double metal wear-resisting hammer crusher in the industry today is the preferred crusher accessories, it has low cost, good abrasion resistance, every tons price is only 15000 yuan or so commonly, but its wearability is equivalent to three times the service life of high manganese steel, so most of the match high manganese steel hammer crusher manufacturers want to, let the customer feel not wear-resisting, then sell high chrome bimetal hammer, is not in the production of hammer crusher manufacturer, and our company is specialized in the production of this kind of high wear-resisting hammer head, but some customers say the hammer head are not wear-resisting, this is so with production process, the following detailed descriptions for you double metal wear-resisting hammer head casting production process.
Bimetal hammer head, from the name is two kinds of hammer, hammer head is worn parts is high chrome material, this material has high hardness, the hammer handle is low chromium carbon steel has a certain hardness, but more important is to wear at the same time, the two materials how to make it a hammer head, there are two kinds of combination process, one kind is cold compound, known as mechanical composition, is the hammer handle to produce first, and then put the hammer head with the hammer handle composite, the hammer head with the hammer handle belongs to cold, no metallurgical combination, in actual use, especially the hammer head easily turn around.The second process is double fluid, the hammer head first molten steel pouring into mold, then add steel hammer handle to mould, this is two kinds of molten steel has formed a metallurgical combine together, the hammer head is not like a cold composite hammer head turn around damage.
Bimetal composite casting was poured simultaneously or successively different melting point of material into a mold or supplement with injection on the workpiece material of bimetallic material production methods.Figure is a typical compound casting double metal wear-resisting casting methods.In addition, the centrifugal composite casting process, the rolling after lawful, explosion welding after lawful, spray deposited after lawful, double continuous casting crystallizer after legal products are widely used in double metal wear resistant composite, such as production.Using rao note method at the same time, two materials at the same time, through different gating system into the separated by a separate board of different cavity.
At this point, the material connection will be done by heat isolation plate in the process of casting.Compound casting gravity method, first will be the first rao molten material into the cavity, the height of the desired, when it set good or is still in the molten state, poured a second material filled cavity.Abrasion-resistant composite casting is another way is to set casting, the pouring molten material in the mold to the preset is, to some extent, the geometry of the workpiece surface between infiltration by preset workpiece heating material, improve the bonding strength, had better be in directly into the mold before pouring molten material workpiece induction preheating preset.
Is more than double metal wear-resisting hammer head casting some introduction, hope to be able to help you.
