Abstract

The invention relates to a heat treatment kiln device and heat treatment method for products such as a super thick plate, a composite plate and the like, in particular to a U-shaped flame reciprocating heating trolley-type heat treatment device and a treatment method thereof. A plurality of sizing blocks are arranged in a row, multiple rows of the sizing blocks are placed in parallel to each otheron a furnace vehicle, and burners are fixed in a staggered manner on the furnace walls on both sides of a furnace and located in gaps between the sizing blocks in multiple rows; the burners, the sizing blocks and workpieces carried on the sizing blocks constitute a U-shaped energy flow channel for energy flow transmission. Side wall burners in opposite arrangement and a simultaneous heating operation system for the traditional trolley-type furnace are changed, the U-shaped flame reciprocating heating trolley-type heat treatment device has the advantages of U-shaped flame unilateral heat supply, U-shaped flame unilateral alternately reversing heat supply, U-shaped flame bilateral reciprocally and flexibly converting heat supply, cyclically reversing heat supply, interval drawing combustionheat supply, and flexible implementation of interval drawing, pulse and reciprocating heating temperature systems. Requirements of different process temperature systems are met, and a sustainable development strategy of energy conservation, emission reduction and clean production is also met.

Description

Technical field

[0001] The invention relates to heat treatment furnace equipment and heat treatment process methods for products such as ultra-thick plates, composite plates and the like, in particular to a trolley type heat treatment equipment and a treatment method for U-shaped flame reciprocating heating. Background technique

[0002] At present, the domestic heat treatment technology for ultra-thick plates and composite plates is relatively backward. Imported roller-hearth continuous annealing furnaces are basically used for heat treatment. Although the performance of imported equipment and treatment processes is excellent, they are only suitable for heat treatment of thin plates, and the investment cost is large. , Maintenance, repair and operation costs are high; and for the heat treatment of ultra-thick plates and composite plates, it is impossible to use this roller-hearth continuous annealing furnace.

[0003] In order to meet the performance requirements of ultra-thick pl...
