TH29610B - Dual utilization machines for continuous annealing and coating - Google Patents

Abstract

DC60 (31/10/44) This invention provides a dual-use machine for annealing and Coated by continuous hot plating method to form continuous annealed steel plates and plates. The steel is coated by hot quenching by alternating production lines in a single machine and according to this invention. A pass-through device is installed to guide the steel plates from the continuous annealing furnace to the water cooling equipment without having to move through the coating pot and coating equipment in the machine The dual benefits of annealing and coating by continuous heat treatment prevent the steel sheet coming out of the annealing furnace from being exposed to the outside atmosphere and being oxidized. During continuous production of annealed products This makes it possible to install two utilization machines. A lower cost solution for continuous annealing and coating applications. This invention provides a dual utilization machine for continuous annealing and heat treatment. To make continuous annealed steel plates and hot-dipped coated steel plates by alternating production lines in a single set of machines, and according to this fabrication, a pass-through device is installed to guide the steel plates. from continuous annealing furnace to water cooling equipment Without moving through the glaze pot and the coating device in the machine, two-way utilization for continuous annealing and hot quenching. This prevents the steel sheet coming out of the annealing furnace from being exposed to the external atmosphere and being oxidized during continuous annealing production. This makes it possible to install a lower cost dual-use machine for continuous annealing and heat treatment.
