Abstract

PURPOSE:To heat uniformly the respective objects to be heated and to obtain heated products having stable quality in a continuous heating furnace by transferring successively the objects to be treated in the direction reverse from combustion gas while rolling said objects on the hearth from the rear end of a preheating zone chamber. CONSTITUTION:The injection gas from a burner injection port 4 is burned in a combustion heating chamber A to a high temp. and the excess hot waste gas escapes through a preheating zone chamber B into a flue C in an upper heating type continuous heating furnace. Objects 13 to be heated such as round bars are supplied successively to the rear end part of the chamber B, where the objects 13 are transferred forward in the direction reverse from the combustion gas while the objects are rolled by each piece on a hearth 2 by each feed apron 8 by the intermittent movement of a chain conveyor 6 in an arrow direction. The heated objects 13 are successively discharged through the discharging port at the front end part of the hearth 2. The rack-shaped teeth 8a provided to the bottom edges of the aprons 8 scrape successively the inside of the continuous groove lines 8 on the top surface of the hearth 2 in this process.

However, - [Second Kiyomimi no Oshikomi fil, 47 upper r? 11
In the heating type yjij (covered outside furnace), the object to be heated is placed on the hearth by the hoop V and placed in the same way as it was!4. Since the gas is fed in sequence, the heat Qn in the gas 4 is such that only the upper 1t14 outer surface ir+1 comes in contact with the burnt ε gas and is heated. JT, it was unavoidable that local heating, unevenness, and the resulting deformation and distortion of the t+ would occur, resulting in a deterioration of quality.Also, the preheating point with a low ceiling Due to the contact between the object and the gas, or because it is a central column, a sufficient preheating effect (11) was obtained evenly, but the thermal efficiency was also poor.

In addition, in order to solve the above nh problem, conventionally, the upper heating part of the furnace was heated to 1 l (11rlJ) of the upper part of the heated object. 1" type continuous heating furnace, or 2 zone 2 14 continuous heating furnace that performs combustion heating in the upper heating zone and lower heating hf in the furnace, etc. There were many disadvantages such as initial roughness (corner) and inability to obtain uniform heating and stable +H air.

This invention was regarded as a vagina in the article 1 of ``Kaede'', and it is intended to provide a continuous heating method of the heating furnace as described below to eliminate the problems of conventional gambling and death. This is what I did.
