Furnace Body
The furnace body is composed of a double-layer cylindrical shell welded to a butterfly-shaped head to form the main body of the furnace. The furnace body consists of a hot chamber, a cold chamber, an oil tank, etc. The hot chamber furnace body is respectively provided with electrode holes, thermocouple holes, temperature measurement holes, vacuum exhaust ports, etc.; the cold chamber furnace body is respectively provided with a middle door square box, a lifting motor hole, an advance and retreat motor hole, a fan motor flange, a vacuum exhaust port, etc.; the furnace door is composed of two butterfly-shaped heads welded to a flange, and the hot chamber, cold chamber, and furnace door are all double-layer water-cooled structures, with water cooling in the middle.
The appearance of the furnace body is uniquely designed by our company and is beautiful and generous.
Vacuum System
The hot and cold chambers of this furnace share a vacuum system, which is composed of a medium vacuum system consisting of an H-70 sliding valve pump, a ZJ-300 Roots pump, and an American Boley vacuum butterfly valve, and is measured by Chengdu Zhenghua's vacuum measurement system. The system has a fast pumping speed and stable performance, and is mainly used for the mid-to-high-end equipment produced by our company. The Roots pump is controlled by a frequency converter, which can adjust the speed of the Roots pump in real time to adjust the vacuum degree and reduce energy consumption, thereby reducing the cost of use
The heating chamber furnace is round and made of carbon steel metal frame, 50MM thick graphite soft felt, carbon rope, etc. The graphite heater is a triangular rat dragon structure, which is independently installed and controlled in the front and rear areas, and the installation is easy and reliable. It is then controlled by control elements such as thyristor voltage regulator, intelligent temperature control instrument, thermocouple, etc. This type of furnace has less heat storage and good insulation effect.
This furnace type has independent temperature control in the front and rear areas. Two thermocouples measure the temperature of the front and rear points and supply it to the British Continental temperature control instrument. The instrument has two independent circuit control functions and high control accuracy, so as to achieve the purpose of small temperature difference between the front and rear and high temperature uniformity.
Oil Stirrer Oil Heater
Lifting System
The lifting system consists of a reducer, a sealing sleeve, a main transmission assembly, a driven sprocket assembly, a trolley, and a small trolley. The lifting operation is directly driven by the reducer. The main transmission shaft directly drives the chain lifting trolley to move up and down; thereby achieving the purpose of up and down movement;
1. There is a guide rod at the rear of the material trolley to prevent the material trolley from sliding forward and backward during the lifting process;
2. The material trolley is designed with a guide wheel to prevent the material trolley from tilting left and right;
3. The material trolley uses special bearings; it has a stronger load-bearing capacity;
4. The material trolley is limited by a gear speed change device; it is more reliable and accurate than the traditional one;
5. The lifting reducer is designed with a brake device, which can be opened manually. The reducer can be manually rotated during a power outage, and is equipped with a rotating handle;
Feeder and return trolley
The moving principle of the feed and retract trolley is that the lever drives the trolley forward and backward. The feed and retract trolley is designed with front position and home position sensing devices, and the movement is sensitive and reliable;
Assistance Systems
Water cooling system:
Each cooling water group is equipped with an independent water flow viewer, which can intuitively view the water flow. Water temperature, water pressure and other alarm devices are set on the water line. When the water pressure is lower than a certain set pressure, an alarm will be issued, and when it is higher than a certain set temperature, an alarm will also be issued. If a water failure alarm occurs, the backup water switching valve will automatically open and switch to the backup water.
Compressed air system:
The system is equipped with a source filter and pressure regulating device at the air inlet, and a pressure detection device. When the pressure is lower than a certain set pressure, an alarm will be issued. And the backup air source switching valve will automatically open and switch to the backup air source.
Inflating system:
A pressure switch is installed on the inflation pipeline. When the pressure in the user's gas tank is lower than a certain set pressure, an alarm will be issued or corresponding treatment will be performed. An imported pressure sensor is installed on the furnace body to detect the pressure in the furnace in real time.
