Vacuum furnace large analytical performance advantage is obvious

Vacuum furnace large analytical performance advantage is obvious
Vacuum furnace, just as its name implies, it operates within the furnace is in a vacuum, so to avoid the defect of the many other each type coal stove.
1, completely eliminates the oxidation and decarburization on the surface of the workpiece during the process of heating, clean surface without metamorphic layer can be obtained. That only when grinding side grinding tool cutting performance greatly improved relations.
2, on the environment pollution-free, "three wastes" treatment is not required.
3, obviously improve the temperature measurement, the monitoring precision. Indicated value of thermocouple temperature and furnace temperature reached plus or minus 1.5 ° c. But in different parts of a large number of artifacts in the furnace temperature difference is bigger, if USES the rarefied gas forced circulation, can still be controlled within + / - 5 ° c temperature difference.
4, high degree of mechanical and electrical integration. Increase in the temperature measurement and control accuracy, on the basis of the workpiece moving, pressure adjustment, power adjustment, etc all can set programming in advance, according to the steps to implement the quenching and tempering.
5, significantly below the salt bath furnace energy consumption. Modern advanced vacuum furnace heating chamber is made of high quality insulation material of insulation walls and barriers, electric energy can be highly focused on indoor heating, energy saving effect is remarkable.

Vacuum furnace production process can be divided into two broad categories

Vacuum furnace production process can be divided into two broad categories
Vacuum furnace production process can be divided into two broad categories: electrolytic method and thermal reduction process, the former USES the vacuum furnace chloride as raw material, the latter using dolomite ore as raw material, etc. Using electrolytic process conditions is the place where power rich and low price. At present only in qinghai and vacuum furnace factory using electrolysis refining vacuum furnace. Under the influence of raw materials, and other factors, our country most of the vacuum furnace factory adopts silicon thermal vacuum furnace smelting reduction method. The method using ferrosilicon as reducing agent, this method is compared with the other vacuum furnace smelting process, the technological process is simpler, less infrastructure investment, factory fast; The production process does not produce harmful gases, slag (2 ca0 si02) for production of cement or fertilizer raw materials; Silicon metal vacuum furnace thermal vacuum furnace smelting process of high purity, large economic benefit. But the size of the reduction pot was numerically simulated small, single canned capacity is low, productivity is low, the thermal efficiency is not high, continuous production, labor intensity is big. Tank outside the solid, liquid or gaseous fuel heating, smoke take away a lot of heat, not only greatly reduces the heat utilization rate, and incomplete combustion of smoke caused serious pollution to the environment.

Vacuum furnace processing technology rapid development, and expand the application range

Vacuum furnace processing technology rapid development, and expand the application range
According to the characteristics of the vacuum brazing process and technical requirements, based on the 3 room of PLC technology to achieve the continuous vacuum brazing of integrated automation system, discusses on the principle of the vacuum brazing brazing, 3 rooms continuous brazing furnace system function, technological process, the function of PLC. With the development of science and technology, make the vacuum heat treatment technology is developing rapidly, expanding the range of application. Be processed materials from titanium, niobium alloy, high temperature alloys, magnetic material to the tool steel, die steel, high speed steel, alloy structural steel, bearing steel, alloy tool steel, spring Huang Gang, etc. The application of the vacuum heat treatment at home and abroad focus on aviation, spaceflight, auto, tools, mold and other industries, and in the automotive industry in recent years, the application of the rapidly, especially in vacuum furnace. And with the advent of 3 rooms the continuous vacuum soldering furnace, realize the continuous brazing process, for enterprises to save production costs, improved the production efficiency, optimize the production process.
