Tunnel Kiln Industrial Electric Furnace High Temperature Kiln
Overview of Tunnel Kiln
Push-plate kiln, also known as push-plate furnace or push-plate tunnel kiln, is a continuous heating sintering equipment, according to the process requirements of sintering products, the required temperature zone and power are arranged to form the thermal part of the equipment to meet the heat demand of the product.
The Working Principle of Tunnel Kiln
1. Place the sintered product directly or indirectly on the push plate with high temperature resistance and friction resistance, and move the product placed on the push plate by the propulsion system according to the process requirements of the product, and complete the sintering process of the product in the furnace.
2. According to the number of parallel push plates in the single furnace body: single push, double push plate; According to the movement direction of the pushing plate in the furnace, it can be divided into reverse and same direction. According to the movement cycle of the push plate, it is divided into automatic, semi-automatic movement, etc. According to the atmosphere of sintering products: oxidizing atmosphere, neutral atmosphere, reducing atmosphere, alkaline atmosphere, acid atmosphere, etc.
3. The temperature control system of tunnel push-plate kiln is controlled by a single circuit intelligent temperature controller imported from Japan; Imported chip SSR module; The main temperature area is measured by domestic high quality thermocouple. The control mode adopts periodic zero crossing control. The propulsion system adopts classic screw propulsion, Siemens PLC logic program control, stepless frequency conversion speed regulation; The high temperature area of the kiln adopts upper and lower independent temperature control.
The Scope of Application of Tunnel Kiln
Tunnel push-plate kiln is suitable for electronic glue discharge, sintering, silver burning of magnetic ceramic products, zirconia porcelain knife glue discharge, zirconia ceramic injection watch chain glue discharge, zirconia granulation powder calcination, lithium cobalt acid battery electrode material and battery cathode material sintering, The sintering temperature of electronic ceramics, structural ceramics, high-aluminum ceramics, chemical materials, electronic components, magnetic materials, electronic powder, luminescent powder (luminescent powder, phosphor) and other products can reach 1700℃.
