     Tubular continuous annealing furnace-stainless steel coil continuous bright annealing furnace structure description Suzhou Jinruier Electric Furnace Co., Ltd. stainless steel coil continuous bright annealing furnace is mainly composed of a discharge rack, a heating furnace body, a water-jacketed cooling box, and a receiving mechanism And other composition. The stainless steel coil bright annealing furnace uses four-zone temperature control, silicon carbide rods or spiral resistance wires are used as heating elements, and the heating temperature can reach 1150℃. The furnace core tube is made of high-temperature stainless steel 310S tube, single layer along the length of the heating furnace Layout, the annealing tube passes through the furnace core tube and is heated. The protective gas adopts an ammonia decomposition furnace to heat liquid ammonia to decompose to obtain a hydrogen-nitrogen mixed gas containing 75% hydrogen and 25% nitrogen, which is sent into the furnace core tube at the same time. The furnace body has a split structure, which is easy to maintain, and the furnace body has good airtightness, low heat loss and good heat preservation.

       In order to quickly cool the annealed stainless steel coil, the annealing furnace is equipped with a water-cooled box, and a stainless steel tube is installed inside as a cooling tube. The annealing tube can be cooled to obtain a supersaturated stainless steel solid solution to achieve the required hardness and brightness of the process. A special winding unit is installed at the rear of the water-cooled box. The tube can be coiled after annealing, and a hydrogen protection input device is installed to prevent the inner hole of the tube from being oxidized. At the same time, hydrogen is fed into the inner hole of the tube for protection to ensure the inner and outer brightness of the annealed tube.

       The continuous bright annealing furnace for stainless steel coils is mainly used for the bright heat treatment of stainless steel wires and tubes such as stainless steel coils and stainless steel wires. Our company is a Suzhou annealing furnace manufacturer, welcome to inquire.
