1.Material selection
Refractory materials:As a key component of the glass furnace, the doghouse needs to withstand high temperatures and erosion by the washout of the glass liquid. Therefore, the choice of material is critical. Common materials include fused cast AZS blocks, which have high refractoriness, erosion resistance and good thermal stability to ensure the long-term stable operation of the charge opening under high temperature environment.
2.Structural design
Reasonable layout:The design of the doghouse should be reasonably laid out to ensure the smooth addition of raw materials and effective pre-melting.
3.Functionality
Efficient feeding:The design of the doghouse fully considers the efficiency and uniformity of raw material addition. Through the reasonable channel and structure design, the raw materials can smoothly and evenly enter into the furnace, ensuring the continuity of glass production and product quality.
Pre-melting effect:The doghouse also has a certain pre-melting effect. Before the raw materials enter the furnace, the preheating and pre-melting of the doghouse can accelerate the melting process of the raw materials, improve the melting efficiency and reduce energy consumption.
4.Durability
High temperature stability:Because the doghouse needs to operate in a high temperature environment for a long time, so its material must have good high temperature stability. The selected material can resist thermal stress and thermal shock at high temperature, to ensure that the long-term use of the doghouse does not crack, peeling and other problems.
Scour resistance:In the process of glass production, the raw materials and glass liquid will have a scouring effect on the doghouse. Therefore, the material of the doghouse also needs to have good scouring resistance to resist scouring erosion and maintain structural integrity.
