The resistance furnace project achieves perfect results

Suzhou Jiuwei Electric Furnace Equipment Co., Ltd. has special insights on the perfect effect of the resistance furnace project

Vacuum electric furnaces are classified according to the degree of vacuum. According to the degree of vacuum, vacuum resistance furnaces can be divided into: low vacuum furnace (~xib'a, high vacuum furnace (~xpa), ultra-high vacuum furnace (pa nozzle. Pointing to a changing The place is called the input place of the change, and the place that the change points to is called its output place. The content of the subject research The subject to be studied in this article is the design of a water temperature control system based on the microcontroller control. The display of the water tank temperature realizes the real-time display and control of the temperature. The low-voltage alternating current is the voltage on the secondary side of the transformer, and the zero-crossing point of the alternating current is detected by the zero-crossing detection electricity. After being sent to the single-chip microcomputer, the two-way control in each sampling period is controlled. The number of sine waves is turned on by silicon to adjust the heating power. In order to comply with the heating characteristics of the silicon molybdenum rod, the nzk voltage regulator has disabled the memory function, so the power should be adjusted from the beginning after each power failure.

In the last century, due to the universal application of graphite materials, coupled with the need for ZigZag, electronics and other industries, the vacuum resistance furnace has grown rapidly, showing various types of vacuum resistance furnaces that can be applied to different process requirements. The technical function, application scale and number of resistance furnaces have been greatly improved and expanded, and they have grown to the goal of automation and intelligent control, high pressure and high flow rate, large-scale and continuous production equipment. Obviously, the power of the thyristor when it is turned on at time 00 of a given period t is the largest. The operation of the transmission idea structure is checked; the water-cooling system is reported to be installed; the function is checked; the sealing function of the 8 furnace is checked. The average area of the furnace wall The area of the furnace wall includes the side walls and the front and rear walls to simplify calculations. The furnace door is included in the front wall. After the air inlet is equipped with the furnace, the bottom is preheated by the heating cavity, and then enters the furnace. The exhaust gas is discharged through the front of the furnace roof and a long-light incineration nozzle is set to burn out the exhaust air to ensure that the air in the furnace reduces the temperature difference in the furnace evenly. The furnace bottom plate is made of cr heat-resistant steel, which is given according to the actual size of the furnace bottom, divided into three or four pieces, thick.

The development and production of vacuum resistance furnaces in our country started in July of the last century. At that time, the primary research was to help discuss the basic properties of vacuum resistance furnaces, heating characteristics, the problem of quasi-fat, and the heating process of metals under vacuum. The basic discipline and deformation problems of the vacuum oil quenching furnace and the vacuum oil quenching furnace and the deformation problems were carried out at the same time. Gas quenching furnace.
