Functional sex is repaired makings the effect that cannot ignore

Functional sex is repaired makings is main use at the special place such as converter, electric stove, finery and steel bag, like hearth, bag bottom, breathe freely brick, brick and slide brick, its technology requirement is easy spread out smooth, good agglomeration and intensity are advanced. Some requirements have permeability, so that repair,breathe freely brick, call breathe freely model repair makings. Drainage is arenaceous the material that is fill tapping mouth, also put in this kind 's charge. This kinds of makings every time dosage is little, but position is significant, as fireproof as functional sex material cooperates to use, friend says functional sex is repaired makings, also call new-style repair makings.

New-style repair makings
Watch 1 for new-style repair the function of makings.
Number 1 with frit of one form report magnesia, intermediate magnesia and spar of electric frit needle are given priority to makings, add small pink of pink of electric frit white corundum and α-Al2O, use organic add; of explosion proof agent with inorganic and compound bond
Number 2 with frit of 2 form report magnesia, intermediate magnesia and agglomeration needle spar are given priority to makings, add a few small pink, also use compound bond and add hurried good dose and; of explosion proof agent
Number 3 with number magnesia of frit of Bai Gangyu of the 4 frit that use phone, report is mixed small pink, add bond and additive, the 5 stone that use zirconium replace number electric frit magnesia.
Number 1 breathe freely for converter bricky magnesium is repaired character makings, number 2 ～ 5 breathe freely for steel bag respectively bricky magnesium is repaired character makings, the brick contains zirconium corundum to pledge vulcanize makings is reached corundum magnesium is filled character all round its seam makings. Breathe freely model repairing the technical key of makings is grain grading and from the reaction, control from agglomeration degree, such ability are obtained breathe freely goodly the effect. Breathe freely brick and water mouth brick expect with cohere makings and juncture commonly, its chemistry composition (%) is Al2O365-86, Cr2O34-15, cohere time is 1 ～ 3min, ≥1Mpa of stoving cohere intensity, ≥6Mpa of intensity of 1500 ℃ cohere. This feed grain comprises the ≥90% that is ≤0.074mm. 　　
Drainage is arenaceous
Drainage is arenaceous be fill of mouth of water of steel bag bottom medicinal powder shape makings, every use stuff, although not be to repair,expect, also have kind of place that be the same as. The technical requirement with arenaceous drainage is, when filling molten steel for long high blandly, its agglomeration layer is not thick, also do not follow molten steel rise, medium, upside is taken to transfer, bottom still holds raw material position in, facilitate leave automatically irrigate stream drip molten steel. Its are main breed has silicon qualitative, MgO-C qualitative, Cr2O3-C qualitative, MgO-CaO is qualitative, magnesian olivine is qualitative, magnesian wait character with Al2O3-ZrO2-C character.
Watch 2 be contain magnesium or contain the function with chromic qualitative arenaceous drainage.
Drainage arenaceous material chooses character, it is a basis steel of steel bag size, smelt is planted and temperature, fine circumstance and Lian Zhu are decided than waiting for a condition, should ensure commonly irrigate steel irrigate rate achieve 90% above.
After when drainage arenaceous material decides character, its grain composition is very important. For example: The grain grading of armour factory is 3 ～ 2mm for 20 ～ 25% , of 2 ～ 1mm for 70 ～ 75% , of 1 ～ 0.5mm for 4 ～ 6% ; The grading of second factory is the ≥55% of 3 ～ 1mm, the ≥45% of 1 ～ 0.5mm. In the meantime, making up when drainage is arenaceous, all add commonly add slippery agent and agglomeration conditioning agent, with period achieve fill close-grained with the purpose with agglomeration appropriate layer. This job mixes next those who carry out experience is directive undertaking in theory of fireproof data base, just can achieve favorable use result.
Zhengzhou Rongcheng acts on the principle that bears the blame to the client, control the tall purity standard of magnesia raw material strictly, ensure magnesian carbon brick of production can be had good high temperature resistant function, the capability that fight broken bits is strong, can get used to a client the moving temperature of actual boiler, product quality was to get more of broad new old user mix reputably all the time support, welcome everybody the incoming telegram seeks advice and choose and buy, flourish Cheng Naicai will act on cordial attitude of attending to guests to the boiler that offers major is transformed and build program to you.
