The information comes from personal work notes, some hands-on experiments, some reference books. Some opinions are just personal thoughts, not correct. Due to the impact of peak-valley stepped electricity price, many induction furnace founds choose night shift smelting, shut down in the morning, intermittent operation. When coming off work in
Application opportunities for induction heat treatment The application of electromagnetic induction in heat treatment has been common. However, the current situation of induction heat treatment indicates that there may be a lot of room for development. The demand for efficiency and environmental protection in the automotive and aviation industries, the
The first step of cooling curve analysis is to visually compare and analyze the time-temperature cooling curves obtained under the same test conditions. The purpose of this visual analysis is mainly to obtain the time required for the cooling transition with different characteristics and the temperature at which it occurs.
Quenching cracks are cracks that occur during quenching or after quenching at room temperature. The latter is also called an aging crack. There are many reasons for quenching crack. When analyzing quenching crack, it should be distinguished according to the characteristics of the crack. There are several common quenching cracks:
High-strength automotive steel can be divided into three generations: the first generation represented by TRIP steel, the second generation represented by TWIP steel, and the third generation steel represented by Q&P steel. In addition to meeting conventional performance indicators such as strength and plasticity, high-strength steel also has some individual
The main factors affecting induction brazing are as follows: 1. Stability and accuracy of induction power supply equipment 1) Precision of power supply control of equipment Usually, the induction heating power supply is output and controlled by the way of current and power. The output precision of the induction power supply directly
When manufacturing mold parts, heat treatment processes are usually used to achieve the required hardness and strength. The metal heat treatment process is to change the surface or internal structure of the material and obtain the required performance by means of heating, heat preservation, and cooling in the solid-state of
Tempered brittleness refers to the embrittlement of quenched steel in some tempering range or slowly cooling from tempering temperature through the temperature range. The tempering brittleness can be divided into the first kind of tempering brittleness and the second kind of tempering brittleness. The first type of tempering brittleness, also known
Why use induction brazing for copper? Induction brazing is a process for joining two metals with a filler material that melts, flows, and wets the metals’ surfaces at a temperature that is lower than the melting temperature of the two metals. Induction brazing for copper has some advantages over other
Metal heat treatment is an important part of the mechanical processing industry, its processing mode in the industry mainly has two different types, different scale of production forms, one is a single small batch of order production, the other is the multi-batch multi-batch mode. In recent years, with the development
