Ask if the company can manufacture an enameling furnace with the following specifications: a continuous, electric tunnel furnace with a high - temperature - resistant mesh conveyor belt; furnace opening height 600 mm, width 1000 mm; operating temperature 845 ???°C; part stay time at operating temperature 180 seconds; common part dimensions: height 350 mm, width 450 mm, depth 450 mm; parts to be enameled weigh 6 kg. Consider a furnace with a total length of 11 meters (4 meters for preheating, 3 meters for 845 ???°C zone, 4 meters for cooling zone), and there must be a temperature transition from the cooling zone to the preheating zone. The final length depends on achievable parameters, and the most important requirement is that parts remain at 845 ???°C for 180 seconds.
