Brass melting furnace for safe operation

Before opening brass melting furnace to check the good electrical equipment, water cooling systems, sensors and other brass is intact, otherwise prohibiting the opening of the furnace. Loss exceeds the melting furnace should be promptly repaired. Prohibited in the Induction forging furnace melt loss over the deep crucible melting. Power transmission and furnace should be the person responsible for the non-contact power transmission sensors and cables. On duty were not allowed to leave their posts, pay attention to external sensors and crucible situation. When charging, induction heat treatment the charge should be checked whether the explosive and other hazardous materials mixed in, if any should be removed and the wet cold material is strictly prohibited material directly into the molten steel, molten liquid filled after large pieces of material joined to the upper forbidden to anti-knot cover.When fettling and pound crucible non iron, iron oxide mixed, pound crucible must be dense. Front pouring induction heating equipment venues and pit should be no obstacles, no water, to prevent the molten steel floor explosion. Steel does not allow costumes too full, hand ladle pouring, the two should be consistent with the walk should be smooth, not allowed Jizou stop, after pouring more than steel to be poured into the designated locations, Dumping is strictly prohibited.

steel melting furnace has what?

steel melting furnace has what? BOF, open hearth, EAF, the other has a vacuum induction furnace, vacuum arc,aluminium melting furnace electron bombardment furnace steel melting furnace using low-ash coal and natural gas, oxygen gas flame heating, and a high speed oxy-fuel burner lance high purity oxygen gas is blown into the melt. steel melting furnace main feature is the pool stirring ability; heat treatment equipment intermittent rotation by appropriate arrangement of the burner and furnace, the reaction can also be expanded; good secondary combustion system of multi-level effects; blowing rate. UHP steel melting furnace in the energy input per unit of time is much higher than ordinary power electric arc furnace, which is equivalent to an ordinary power electrode sections are not competent.High Frequency Induction Increase the electrode section will make it support, drive and even bulky structure of the entire furnace, but also cause difficulties for the control system.

Arc melting furnace main features

1: arc melting temperature up to 1980 ° C the melting furnace, the refractory metal most meltable.
2: melting time of 30-60 seconds,induction heating equipment minimizing volatile elements.
3: violent arc ignition, so that kind of completely melt mixing, excellent homogeneity.
4: Water-cooled copper crucible, the sample easily emerge without a release agent, and will not cause cross-contamination of samples and the crucible.
5: melting high purity argon environmental samples.
6: arc melting furnace,induction heating equipment small size, simple operation, without routine maintenance.

Melt furnace type

Melt furnace gas sub-type and two electric melting furnace.
Gas type advantages:Induction heating equipment suppliers observation sample molten state at any time, easy operation, low price. Cons: not as good as electric melting furnace precise temperature control required laboratory gas conversion.
Electric melting furnace advantages: high degree of automation, precise temperature control,induction melting furnaces a melting like a few more. Cons: Can not observed sample molten state.

Advantages steelmaking furnace

High power electric arc steel melting furnace has outstanding advantages, but must have the following conditions in order to give full play to the role:
 ① strong supply network.Induction welding equipment Short circuit capacity should be more than 80 times the maximum capacity of the furnace transformer. Or install a huge capacitor compensation device (the high cost of doing so) to reduce voltage fluctuations on the network, so affect the normal operation of other electrical equipment.
 ② high power electrodes. UHP unit time input energy is much higher than ordinary power electric arc furnace, which is the same cross-section of the general power of the electrode is not competent. Increase the electrode sections will make it support, drive and even bulky structure of the entire furnace, but also cause difficulties for the control system. High power electrode is a material needle pitch, the electrode having a crystal structure orientation. Its electrical conductivity, thermal conductivity, oxidation resistance, strength and other properties are better than ordinary power electrode of the same section.
③ efficient production management system. High power electric furnace for 19 survey results indicate that about 20% to the effects of ultra-high-power, 60% played only 60 to 70 percent of capacity,High Frequency Induction while 20% are not functioning. Among them, the production organization and management is extremely important, not simply that, with a large capacity electric arc furnace transformer will be able to achieve the desired objectives.
As a result of high power electric arc steel melting furnace and various refining method, an arc steel melting furnace melting apparatus serving as a simple trend; steel and configuration adapted to the production and refining equipment, the use of the furnace transformer in order to fully ability to improve steel production.

Gold melting equipment advantages

Gold melting equipment advantages: light weight, small size, high purification efficiency, easy installation,induction heating equipment simple operation, fast heating, the heating temperature is constant. Gold melting equipment operation safety and environmental protection. Protection of the whole: with over voltage, over current, into heat, water and other alarm devices and automatic control and protection.gold melting furnaces Gold melting equipment s mainly through the crucible container after the precious metal instant induction heating, melting, purification, casting and other processes.
