(Prior Art) Conventionally, a conveyance device for moving objects in a furnace has, for example, two chain receiving rails arranged side by side at a predetermined interval in the furnace, and a chain is installed on these rails. The chain moves in a circular manner through the outside of the furnace and back into the furnace. The chain is provided with a holding section on the inside of which the object to be transported is placed, and is driven by a sprocket or the like that is linked to the prime mover, and slides on the rail to carry the object to be heated out of the furnace. The material is then heated while being moved inside the furnace, and then transported out of the furnace.

By the way, since the chain receiving rail described above is constantly exposed to high temperatures in the furnace, a reinforcing material is provided on the outer side of the chain receiving rail to prevent warping due to heat or to strengthen the structure.
The reinforcing material is composed of a plate-shaped horizontal reinforcing material and a plate-shaped vertical reinforcing material in order to improve the strength of the chain receiving rail in the horizontal and vertical directions, and the horizontal reinforcing material is a flat plate. The vertical reinforcing members are arranged and fixed with the flat plate portion vertical, and are reinforced in each direction.

(Problems to be Solved by the Invention) By the way, in such a conveying device used in a high-temperature atmosphere, the chain circulates between the inside and outside of the furnace, so the temperature is relatively low. Therefore, the inner side of the chain receiving rail that receives the chain tends to be at a low temperature. The chain receiving rail is long and has a reinforcing material, so it has a large heat capacity and easily absorbs heat from the vicinity. For this reason, if the transported object heated to high temperature in the furnace is near this chain receiving rail, the temperature of the transported object near the holding part closer to the chain receiving rail will drop, and the temperature of the transported object will become unstable. There is a problem in that the heating becomes uniform and it becomes difficult to effectively heat and retain heat of the transported object.

The long rail 2 consists of upper and lower rails 2a and 2b, and a roller 3a of the chain 3 is movably held between the upper and lower rails 2a and 2b. Among the rollers 3a that are chain members, the roller 3a supports at least the conveyance pin 6 that holds the conveyed object.
An auxiliary member 4 having approximately the same diameter as the roller 3a is connected to the inner surface of the roller 3a.

A heat shield plate 5 is provided on the inner surface of this auxiliary member 4.
The peripheral edge of the heat shield plate 5 is configured to protrude from the outer peripheral surface of the auxiliary member 4. Furthermore, the conveyance pin 6 is erected at the center of the inner surface of the auxiliary member 4, and objects to be conveyed are placed on the opposing conveyance pins 6, 6.

According to this chain, the conveyor pins 6, 6 are used as the holding parts for the conveyed objects, and they are located apart from the rail 2, which has a large heat capacity, so that heat conduction is hindered, and the heat shield plate 5 prevents radiant heat. Since it is blocked, it is possible to prevent thermal effects on the transported objects as much as possible. In particular, the peripheral edge of the heat shield plate protrudes from the outer peripheral surface of the auxiliary member 4 to prevent the auxiliary member 4 from being heated by radiant heat.

(Effect of the invention) As explained above, according to this invention, in a chain movably installed on each of two long rails installed in parallel in a furnace, a holding part that holds an object to be conveyed is provided. An auxiliary member provided with a heat shield plate is connected to the inner surface of the chain member supporting the
Since the holder for the conveyed object is provided inside this auxiliary member, the conveyed object that is susceptible to heat can be placed away from the rail, which has a large heat capacity, and the radiant heat can be blocked by the heat shield plate. , the influence of heat on the transported objects is prevented as much as possible. Therefore, there is an effect that heating and heat retention of the transported object can be kept uniform and in a good condition.

In addition, since the heat shield plate is provided on each auxiliary member and has its peripheral edge protruding from the outer peripheral surface of the auxiliary member, it is possible to prevent heat dissipation from the transported object supported by the holding unit as much as possible, and also prevent the auxiliary member from dissipating heat as much as possible. This has the effect of preventing heat from being transferred as a result. Heat dissipation from the transported object is conducted heat (contact with the holding part) and radiant heat. The conductive heat can be sufficiently reduced by protruding the holding part and using it as a conveying pin, and the radiant heat can be reduced as described above.
Install a large heat shield at the closest point to block the heat and prevent radiation.
