ceramic ferrule for stud welding

Ceramic ferrule for stud welding of main chemical composition is 2MgO*2Al2O3*5SiO2, adhere to control the content of  impurities with the raw materials of high purity, pure and stable chemical composition in the process of sintering or calcined materials, bring customers more added value.The dry pressing and sintering of 1300 degrees of high temperature, the control of temperature can be accurate to within plus or minus 1 degree Celsius for ceramic ferrule sintering. At the same time, strict control the advancing time and holding time for product in the furnace, in order to achieve the best result for ceramic ferrules, with a very low thermal expansion coefficient, excellent electrical insulation.
