What is quenching equipment, how to detect quenching effect

Quenching is a heat treatment process for steel, which requires the use of related machinery and equipment. The following is a small series of friends to introduce the relevant expertise of quenching furnace equipment, how to distinguish between intermediate frequency and power frequency quenching equipment, how to come Check the effect of quenching, the following one for the friends to introduce in detail.
 What is the quenching furnace machine equipment?
Dongguan Haitu quenching equipment refers to the machine equipment for solid solution treatment of materials or heat treatment process with rapid cooling process. Including medium frequency quenching furnace, high frequency quenching furnace, power frequency quenching furnace, numerical control quenching machine, integrated quenching machine. The quenching equipment itself consists of a combination of a quenching machine, a medium and high frequency power supply, and a cooling device.

Quenching effect: hardness requirements and test methods for workpieces of quenched products
The hardness of the workpiece of Dongguan Haitu quenching product affects the quenching effect. Hardened product parts are usually tested for HRC hardness using a Rockwell hardness tester. The hardness of the HRA can be tested on hardened thin hard steel and surface hardened workpieces. For quenched steel sheets with a thickness of less than 0.8 mm, workpieces with shallow surface quenching products, and quenched steel rods with a diameter of less than 5 mm, the surface hardness tester may be used to test the hardness of HRN. When welding medium carbon steel and some alloy steels, quenching may occur in the heat-affected zone and become hard, which is easy to produce cold cracks, which is to be prevented in the welding process. Since the metal material is hard and brittle after quenching, the residual surface stress will cause cold cracking, and tempering can be used as one of the means to eliminate cold cracks without affecting the hardness. Quenching is suitable for thin and thick parts. For oversized parts, the quenching depth is not enough, and carburizing has the same problem. In this case, alloys such as chromium should be added to the steel to increase the strength. Quenching is one of the basic means of strengthening steel materials. Martensite in steel is the hardest phase in iron-based solid solution structure (Table 1), so steel parts can be quenched to obtain high hardness and high strength. However, the martensite is very brittle, and after quenching, there is a large quenching internal stress inside the steel, so it is not suitable for direct application and must be tempered. Microhardness value of iron-based solid solution in steel.
The quenching process is widely used in today's machinery manufacturing industry. The important parts of the machine, especially those used in automobiles, airplanes and rockets, are basically quenched. In order to meet the technical specifications and requirements that require a wide variety of components, a variety of quenching processes have been developed in the future. For example, according to the treated part, there are integral, local quenching and surface quenching; whether the phase change is complete under heating, there is complete quenching and incomplete quenching (for hypoeutectoid steel,
The method is also called subcritical quenching); according to the content of phase change during cooling, there are graded quenching, austempering and underspeed quenching.

How to distinguish between medium frequency and power frequency quenching equipment? The medium frequency quenching power supply has a frequency of 1-10KHZ and a quenching depth of 3-5mm. It is equipped with vertical and horizontal machine tools for heating the slender shaft. The frequency of the power frequency power supply is 50HZ. There are starter cabinet, balance cabinet and compensation cabinet. The quenching depth is 3-5mm, and it is equipped with vertical machine tools. The most notable features in the IF power supply are thyristors (thyristors), which have power capacitors.
