Strict Production Process Gb 42crmo Material Alloy Tool Steel Supply - China

Production process The production process of GB 42CrMo material includes steelmaking, continuous casting, rolling, annealing and finishing.

In the steelmaking stage, molten iron is refined by electric furnace or converter to remove impurities and gases to obtain pure molten steel.

Subsequently, the molten steel is injected into the continuous casting machine for continuous casting to form steel plate billets.

The billets are subjected to the rolling process to obtain steel plates of different specifications and thicknesses.

In the annealing stage, the steel plate eliminates internal stress and improves plasticity and toughness by controlling the temperature and cooling rate.

Finally, after finishing, the surface of the steel plate is smooth and flat to meet customer needs.

The production process of GB 42CrMo material mainly includes the following steps: Material selection and smelting: First, select raw materials with stable chemical composition and high purity, such as iron, chromium, molybdenum, etc.

These raw materials must be strictly inspected to ensure that their quality meets production requirements.

Then, these raw materials are smelted at high temperature to form the liquid form of the alloy.

During the smelting process, factors such as temperature, time and atmosphere must be controlled to ensure that the composition of the alloy is evenly distributed and to avoid the generation of harmful impurities and gases.

Casting: Pour the liquid alloy into the mold and solidify it into a solid alloy after cooling.

The design and manufacture of the mold are crucial to the performance and appearance of the alloy.

The cooling rate and temperature gradient need to be controlled during the casting process to avoid defects such as cracks and pores.

Forging: Forging is the core process for manufacturing 42CrMo round steel forgings.

Before forging, the round steel billet needs to be heated to a suitable temperature to ensure that it has good plasticity and forgeability.

Then, the heated round steel billet is placed on the forging equipment and plastically deformed by applying pressure to change its shape and structure.

Heat treatment: Heat treatment is a key step in the production process of GB 42CrMo material.

The internal structure and properties of the steel are adjusted by heating and cooling treatment.

For 42CrMo, heat treatment processes such as quenching and tempering are often performed to obtain the required properties such as hardness and toughness.

During the heat treatment process, parameters such as temperature and time need to be strictly controlled.

Machining: After forging and heat treatment, 42CrMo round steel forgings need to be machined to obtain more precise and required dimensions.

Machining includes turning, milling, drilling, boring and other processes.

Rolling: For the production of steel plates, the molten steel needs to be processed into steel plates of different specifications through a rolling mill.

During the rolling process, the steel needs to be cooled and adjusted several times to obtain the required properties such as hardness and toughness.

Finishing and surface treatment: The steel after rolling or forging is surface treated and finished to meet customer needs.

This includes removing burrs, scales, etc.

on the surface of the steel, as well as rust and corrosion prevention.

Quality inspection and control: During the production process, quality inspection and control are also required for each link to ensure the quality and stability of the final product.

This includes the use of high-precision testing equipment and methods to conduct comprehensive inspections on the size, shape, composition and performance of the steel.
