Forging heating furnace is v workshop heats the basic heating installation that forge expects. Its main characteristic in had produced Cheng is: V breed much, norms volume of weight of forging of small; of much, batch is differ, small a few grams, go to hundreds of tons greatly, consequently, forging the sort of heating furnace is much, and the dimension of size furnace differs very big. Chooses furnace also with respect to each not identical. But with respect to its hot industry system is told nothing more than constant temperature heats (first phase heats) and change furnace temperature is added by (2 period reach much period heat) . Be less than the poor capable person of 0.5 and excessive material to Bi multi-purpose first phase heats, and Bi is more than the thick material of 0.5 to be used more 2 period reach much period heat. Heat eventually temperature basis steel is planted different and different. Usually, heat temperature is between 1150〜1280 ℃ , this temperature is fireproof to choosing the very main effect since material.
Forging because heat,the another job characteristic of furnace is; steel is planted, norms, batch, the reason such as dimension, cause forging furnace production basically is to show discontinuity and periodic. Accordingly, forging the body of build by laying bricks or stones of furnace bilges at the heat of periodic change cold in the harsh environment that shrink. Put on the reason of makings, put on makings furnace door to need to often be hit and shut, the fireproof material that makes furnace door is in produces the change of urgent cold urgent heat.
Stage car type forgings furnace is sealed to car bottom also be crucial. Sealed and lax may inspiratory air cooling drops furnace temperature, increase the amount containing oxygen in only waste time and flue gas, expect if,base oxidation increases; thereby sealed and undesirable, pressing when furnace when, high temperature flue gas is easy outside excessive, burn down arenaceous the equipment end Liang Jilu of car of stage of an establishment, hearth. Anyhow, ask to often be safeguarded, complement is fine arenaceous, sealed be in exact position.
To existence oxidation atmosphere forging furnace, it is inevitable that forging produces ferric oxide skin because of oxidation. Be in so choose hearth when fireproof material, notice hearth is fireproof material does not have chemical reaction effect with ferric oxide skin.
Forging of furnace put on makings can divide for mechanical and manpower type two kinds. No matter be which kinds of circumstance, material semifinished product and hearth can produce contact and clash, or with put on makings mouth fireproof material produces collision, make the fireproof material of hearth or furnace door is worn away thereby with damaged, force of special choose and employ persons is put on when makings, this kind of case is more severe. Accordingly, divide in producing a course outside wanting to reduce this kind of loss as far as possible, choose wear-resisting even, fight percussive hearth of fireproof material build by laying bricks or stones and put on makings mouth.
