Technical Breakthrough Of 1 2312 Material In Controlling Sulfur Element - China

DIN 1.2312 steel is a plastic mold steel with excellent cutting performance.

The 1.2312 material increases the content of S element compared to 1.2311 steel, and the addition of S element can improve the cutting performance of the steel.

However, S element is a harmful element that can easily combine with other elements in the steel to form sulfides, which can reduce the plasticity and toughness of the steel and easily cause hot cracks during processing, So, in order to ensure the steel performance and improve the cutting performance of 1.2312 steel, while taking into account production costs and benefits, we have made breakthroughs in controlling sulfur elements technology in Songshun Steel.

In order to solve the influence of S element on the performance of 1.2312 steel to a certain extent, controlling the content and distribution of sulfur element is a key technical breakthrough point.

This article will discuss the technological breakthroughs in controlling sulfur from several aspects.

Raw Material Selection And Pretreatment

The chemical composition of raw materials is strictly controlled, and high-quality materials with low sulfur content are selected as raw materials for 1.2312 steel to reduce the initial content of sulfur elements.

Pretreatment measures can also be carried out, such as vacuum furnace smelting and high-temperature desulfurization, to minimize the sulfur content in raw materials.

High-temperature desulfurization mainly promotes the dissolution of lime, improves the fluidity of slag, etc.

through the increase of temperature, that is, improves the kinetic conditions of desulfurization, thereby accelerating the speed of desulfurization.

It can also be desulfurized through the converter, but the efficiency is relatively low.

Generally, molten iron pretreatment is used to reduce the desulfurization pressure of the converter.
