·GKT series furnaces include: GKT series composite quick heating temperature spheroidal annealing furnaces, GRT series electric heating pre-pumped vacuum protective atmosphere temperature spheroidal annealing furnaces, GZH series roller-hearth composite heating isothermal normalizing furnace, GKT series composites heating re-crystallization anneal furnace, etc. The above mentioned products have reached the top level of the sector with national patents.

·By pumping vacuum at the two ends of the furnace and then filling it with Nitrogen, GRT series electric heating pre-pumped vacuum protected temperature spheroidal annealing furnaces realizes non-oxidation annealing of the work pieces. The equipment performs with small atmosphere, low consumption of energy and easy subsequent cleaning.

·GKT series composite quick heating isothermal spheroidal anneal furnace realizes the quick heating and greatly reduces the annealing time and the decarburization degree and level; the decarburized level is around 0.12-0.16mm.

·GZH series roller-hearth isothermal furnace is suitable for spheroidal annealing of bearing ferrule, round steel, steel tube, alloy-steel, and is also widely under application in the pre-heat treatment before precise forging, sold rolling, cold rectifying and cold expanding.

·GKT series furnaces are designed carefully to meet all the technique requirements. The temperature control is accurate, the operation is simple, and the processing is reliable with very low energy consumption.

·The annealing quality is better than standard JB/T 1255-2001. The internal structure of the annealed workpieces is uniform and fine. The objective to anneal effectively, continuously and energy-efficiently is accomplished.
