The hollow particle protects the production line of dreg The hollow particle protects the dreg Protect the characteristic of the dreg Advance of the technological craft 　　 Whom our factory produce person who melt hollow particle cast , protect dreg department adopt foreign advanced technological craft and prescription organize , produce in succession in advance, all raw materials technical standards according to foreign countries used are purchased, the domestic producer can't meet the demands , adopt and import raw materials; The production equipment adopts the domestic and related the whole stainless steel apparatus of inside lining; Melt , heat , dry , adopt reasonable fuel heat technology most , to control harmful impurity to protect dreg extremely favorable in advance. Can follow different steel kind draw the speed with difference of casting machine, allocate various composition content, get different steel kind and different person who cast take different kinds of (alkalinity, melting point, viscosity, density, crystallization temperature, moisture content,etc.) person who melt open particle casts and protects the dreg even in advance, meet different users' difference's needs, can also develop the special protection dreg of the special requirement for users at the same time .   Dependability for producing apparatus 　　 Protect the production equipment of dreg a whole set ofly and include the compounding system (12.5m3 , 3.7m3 ), 5m3 servo system, 1000 type to spray dry tower, three empty and getting cold belt transport material machine , 5m3 store the material storehouse and examine one jin of packaging systems automatically. Possess , produce 15000 person who melt hollow particle cast production capacity to protect the dreg in succession in advance every year, through produce as a trial , run , prove a complete set of equipment operate , stabilize , control the temperature accurate spraying , building grain accord with hollow , even steady production requirement; Complete set take examine apparatus can analyze chemical composition and various thing index of products accurate, can meet every steel factory different steel kind cast , produce necessary of different types protection actual need that dreg produce in succession. Product quality guarantees the measure 　　 In order to guarantee to protect the product quality of the dreg , have specially established and melted to examine the centre, allocate 7 people, have a academic certificates at or above the junior college level . Invest more than 600,000 yuan in melting and examining the apparatus , buy GX - ⅢType high-temperature thing tester, HR- 3C type gray melting point measure apparatus, analytical balance of Model TG328A, 9516 type metal make carbon appearance, 90mm agate mortar, box resistance furnace of SRJX- 4- 1 type high temperature, 202- 2 type electric heat thermostatical drying cabinet , 721 type spectrophotometer and atom absorb spectrophotometer and titration complete set used to analyze take , examine analytical equipment, have offered fully reliable melting and examining the means of analyzing for guaranteeing product quality, offer the reliable analysis data for protecting the dreg products intactly. Production protects all raw materials that the dreg uses to purchase according to foreign countries standard, test batch of 100 to the raw materials which enter the factory.
