Vacuum Industrial Furnace Advantages

1. The oxidation and decarbonization of the workpiece surface during heating can be eliminated completely, and the clean surface without deterioration can be obtained. This is of great importance to the improvement of the cutting performance of tools that only grind one side when grinding, such as twist drill grinding, which directly exposes the decarburized layer on the groove surface to the edge.

2. It does not pollute the environment and does not need to dispose of the three wastes.

3. The accuracy of furnace temperature measurement and monitoring has been greatly improved. The indication value of thermocouple and furnace temperature reach (+1.5) C. However, the temperature difference in different parts of a large number of workpieces in the furnace is large. If the forced circulation of rarefied gas is adopted, the temperature difference can still be controlled within the range of (+5) C.

4. High degree of mechatronics. On the basis of improving the accuracy of temperature measurement and control, workpiece movement, air pressure regulation and power regulation can be programmed in advance, and quenching and tempering can be carried out step by step.

5. Energy consumption is significantly lower than that of salt bath furnace. The heating chamber of modern advanced vacuum industrial furnace adopts insulation wall and barrier made of high quality thermal insulation material, which can highly concentrate the electric heat energy in the heating chamber, and the energy saving effect is remarkable.

Vacuum Hot Press Furnace System

Vacuum hot pressing furnaces are usually composed of several mechanical systems, as follows:

1. Vacuum system: It consists of oil diffusion pump, Roots pump, mechanical pump distribution electromagnetic pressure differential valve (to prevent sudden power outage, mechanical pump oil backfilling) inflatable valve, exhaust valve, vacuum butterfly valve, vacuum pressure gauge (+Pa) bellows, vacuum pipeline and support.

2. Hydraulic system: electric input mode is adopted. The hydraulic station is equipped with imported proportional valves, pressure sensors, displacement display, grating ruler (ranging accuracy 0.02 mm), hydraulic cylinder and other related hydraulic devices. The pressure regulation is semi-automatic and can be adjusted manually. The instrument can set the pressure automatically, and can realize voltage stabilization and holding.

3. Water cooling system: It is composed of various valve and pipeline related devices and has the function of automatically cutting off heating source or function of water-cut sound and light alarm.

4. Temperature control system: SCR is used to control temperature, equipped with PID function instrument and digital display meter. It has the function of over-temperature sound and light alarm. PLC touch screen can also be used to control temperature automatically, and historical data can be retained to facilitate the analysis of sintering process.

5. Inflation system: It is composed of various pipelines and valves, and equipped with electromagnetic vent valve and pressure sensor. When the pressure in the furnace is higher than the safety value, it will automatically vent. The inflatable pipeline is equipped with needle valve, which can control the inflatable volume.
