Abstract

PURPOSE:To enable common use of a hearth part for conveying heating materials having different lengths such as long-sized materials and ingots and to improve the heat unit by installing walking hearths and walking beams in combination to said hearth part. CONSTITUTION:A walking frame 5 moved vertically and transversely by a driving device 8 makes walking operation. Movable beams 3 and movable hearths 4 are fixed to the frame 5 and makes the same operation as the operation of the frame 5. An extra-short material 7 is alternately supported by a hearth 1-1 which is a part of a furnace body 1 and the hearth 4 and is conveyed by the walking cycle of the hearth 4. A long-sized material 6 is alternately supported by stationary beams 2 fixed to the hearth 1-1 which is a part of the body 1 and the beams 3 and is conveyed by the walking cycle of the beams 3.

In walking-type heating furnaces, in addition to the in-furnace transport by transferring materials between a fixed beam and a movable beam installed in the furnace (i.e., walking beam type), a movable hearth is installed in the hearth section, and the fixed hearth and movable hearth This heating furnace is characterized in that it also enables transport within the furnace (that is, a walking hearth type) by transferring materials.

ると加熱炉の熱原単位（熱効率）が悪化する。In the case of a walking beam type heating furnace, the number of beams is designed to be minimized by considering the material arrangement depending on the material length conditions. However, if the material contains extremely short materials such as ingots whose length is far different from the length conditions of general materials, the pitch of the beams should be set closely so that the extremely short materials can also be transported. There must be. Since the beams are generally water-cooled, increasing the pitch of the beams deteriorates the heat unit (thermal efficiency) of the heating furnace.

It is intended to be transported.

A movable beam 3 (walking beam) and a four-piece movable hearth are fixed to a forking frame 5, and move in the same way as the walking frame 5. The extremely short materials 7 are alternately supported by the hearth 1-1, which is a part of the furnace body 1, and the movable hearth 4, and are transported by the walking cycle of the movable hearth 4 (movable walking hearth). The long materials 6 other than the ultra-short antiphase 7 are fixed to the hearth 1-1, which is a part of the furnace body 1, and are alternately supported by the fixed beam 2 and the movable beam 3, and are supported by the walking cycle of the movable beam 3.
