Problems solved by technology

[0006] However, because the momentum of the free jet is conserved on each section, the free jet ejected from the nozzle, due to the momentum exchange of the molecular microgroups and the surrounding gas, makes the surrounding gas flow with the jet gas, resulting in an entrainment effect. , the velocity of the jet gas at the cross-section decreases, the mass of the jet gas at the cross-section increases, and the kinetic energy of the jet gas decreases. As a result, the jet gas screen cannot effectively block the flow of hot gas in the heat preservation section to the cooling section, and cannot keep the furnace pressure stable.

Abstract

The invention relates to a wall-adhered jet seal pressure stabilizing device in a galvanized strip steel alloying process and an application method thereof. The device mainly consists of an air box, anozzle, a movable side plate, a flow stop plate, a support column, an upper slide way and a lower slide way; when the movable side plate is located in a closed state, the support column fixedly connected to the movable side plate horizontally supports the flow stop plate; at this time, the distance W from the end part of the flow stop plate to galvanized strip steel is 30-60 mm, so that the winding and sucking effect on the lower side of free jet is reduced; when the movable side plate is opened by moving to two ends of the upper slide way and the lower slide way, the flow stop plate is rolled over under the effect of gravity to locate in a vertical state; and at this time, the distance from the plane of the flow stop plate to the galvanized strip steel is equal to the distance from the nozzle to the galvanized strip steel. The device can effectively stop hot air currents of an insulation section of the galvanized strip steel from upwards ascending, and meets the insulation requirements of the insulation section of the galvanized strip steel on the basis of not influencing the surface quality of hot galvanized strip steel.

Description

technical field [0001] The invention belongs to the technical field of heat preservation of galvanized strip steel, and in particular relates to a wall-adhesive jet sealing and voltage stabilizing device in the alloying process of galvanized strip steel and a use method thereof. Background technique [0002] Due to its low production cost, good corrosion resistance, coating performance, welding performance and impact resistance, hot-dip galvanized steel sheet is very suitable for high-end hot-dip galvanized product consumption industries such as automobiles and home appliances, and can meet the needs of users. The quality requirements of high-quality surface characteristics and good internal performance of products. The hot-dip galvanized steel strip output from the zinc pot usually needs to complete multi-stage heat treatment in the alloying furnace. The stability of the alloying reaction temperature required in the cooling section is relatively high, and if there is a sli...
