Electric smelting fused cast AZS choice principles

Electric smelting  fused cast AZS  before I need to first understand the following factors: 
(1)Pond furnace used period;
(2) Glass quality requirements;
(3) Production capacity, namely, rates of melting and melting temperature selection,
(4) insulation, what parts to conserve fuel needed in insulation; 
(5) economy, namely investment. Optional Electric-melting electro fused cast AZS , to meet the application requirements, ensure furnace economy, ease of manufacture. 
1. that access requires the construction of glass tank furnace with electric smelting fused cast AZS  should meet the following basic requirements: 
(1) should have a high softening, melting temperature, generally at least 1580 refractoriness ° c. 
(2) it has sufficient mechanical strength, resistance to impact, friction, erosion of high speed flame, smoke and other mechanical function.
(3) high-temperature structural strength, and operating temperatures can long withstand mechanical loads.
(4) Fusion, fused glass and batch components gaseous substances corrosive resistance is strong. 
(5) small glass contamination. 
(6) thermal shock resistance (thermal shock). 
(7) good volume stability of high temperature, residual shrinkage or expansion is very low.
(8) heat capacity, thermal expansion, thermal conductivity, thermal properties meet the application requirements. 
(9) the electric smelting  fused cast AZS shapes structured, accurate. 
(10) in accordance with requests for other conditions of use. Must be based on erosion of furnace parts with different criteria to select Electric-melting  fused cast AZS.
