The causes of deformation of precision and complicated molds are often complicated, but as long as we master the deformation rules and analyze the causes, the use of different methods to prevent mold deformation can be reduced and controlled... (more…)

Be sure to apply anti-corrosion paint before use.Always clean the scum on the edge of the crucible when using it. Ladle out the aluminum liquid in the crucible during long-term shutdown, clean the hanging slag on the crucible wall, and apply... (more…)

Trolley resistance furnace is the main furnace type in the heat treatment industry. It is responsible for the heat treatment production process of large castings and forgings. Standard trolley resistance furnace operation and daily maintenan... (more…)

Electric furnace: Electric heating equipment that uses electric heating to achieve the intended technological purpose (such as smelting, melting, heating, heat treatment, sintering, drying, etc.) is called an electric furnace. The industrial... (more…)

The design of ordinary heat treatment industrial resistance furnace mainly considers the key parts such as furnace frame, furnace shell, furnace lining and furnace mouth device.... (more…)

Common defects in quenching include oxidation, decarburization, deformation, cracking, overheating, over-burning, insufficient hardness, soft spots, soft spots, etc., among which oxidation, decarburization, overheating, deformation and crack... (more…)

Advantages of the inverted trolley furnace The inverted trolley furnace saves energy and reduces production cost: due to the structure of the whole fiber furnace and the good thermal insulation performance, it can save about 1/4 of the energ... (more…)
