Description

A furnace door guide

technical field

The utility model relates to the field of steel rolling heating furnace equipment, in particular to a furnace door guide groove.

Background technique

A furnace door bottom plate is usually arranged at the furnace door of the steel rolling heating furnace, and the furnace door bottom plate is used to allow steel billets to enter and exit, so as to avoid damage to the furnace door due to impact and friction of steel billets. However, the existing furnace door bottom plate has a simple structure, which is simply a plate structure fixed at the bottom of the furnace door. The existing furnace door bottom plate is short in length, has no pour on the end face, and the installation is unstable. The steel billet is easy to hit the bottom plate and the furnace The wall and bottom plate lack guides, and the billet is easy to deviate or hit the furnace wall and the equipment at the end of the furnace when it comes out of the furnace.

Utility model content

The technical problem to be solved and the technical task proposed by the utility model are to improve the existing technology, provide a furnace door guide groove, and solve the problem that the furnace door bottom plate is prone to hit the bottom plate or furnace wall in the current technology, and the non-guided steel billet is easy to The problem of deviation.

For solving the above technical problems, the technical solution of the utility model is:

A furnace door guide groove, comprising a base plate, characterized in that vertical guide plates are arranged on both sides of the base plate, a U-shaped groove structure is formed by the guide plates and the base plate, and pin grooves for installation are also opened on the base plate, Install the furnace door guide groove on the furnace wall through the pin groove. The furnace door guide groove described in the utility model changes the traditional flat furnace door bottom plate into a U-shaped groove structure, uses the guide plates on both sides of the bottom plate to play a guiding role, and prevents the steel billet from hitting the two sides of the furnace door, so that The steel billet can enter and exit smoothly along the furnace door guide groove, thus effectively protecting the furnace wall.

Further, the length of the bottom plate is consistent with the thickness of the furnace wall, and can go deep into the furnace door, so that the steel billet does not need to contact the furnace wall first and then the bottom plate, thereby preventing the steel billet from hitting the inner side of the furnace wall and strengthening the protection of the furnace wall. The front end inside the furnace wall is a wedge-shaped structure, which plays a good role in buffering and guiding, avoiding the collision between the steel billet and the end face of the bottom plate, effectively protecting the bottom plate and prolonging the service life of the bottom plate.

Further, the front and rear ends of the guide plate are set as wedge-shaped structures, and the wedge-shaped structure also plays a role of guiding and buffering, so as to avoid collision with the end face of the guide plate when the steel billet enters and exits, protect the guide plate, prolong the service life, and Guide the direction of billet in and out to avoid collision of billet deviation.

Further, the rear end of the bottom plate is provided with a laterally widened rear plate, which can enhance the stability of the installation of the furnace door guide groove, so that the furnace door guide groove can play a good role in guiding and protecting the furnace wall.

Further, the thickness of the rear plate is greater than that of the bottom plate, which increases the weight of the guide groove of the furnace door and enhances the installation stability.

Further, the end surface of the rear plate is set as a wedge-shaped structure, which acts as a guide and buffer, and prevents the steel billet from hitting the furnace door guide groove when the steel billet is poured back into the heating furnace.

Compared with the prior art, the utility model has the advantages of:

The furnace door guide groove described in the utility model effectively protects the furnace wall and prevents the steel billet from hitting the furnace wall, and the furnace door guide groove is set as a wedge-shaped structure on its end face, which plays a good guiding and buffering role and prevents the steel billet from being guided by the furnace door. Collision occurs when the grooves are in contact, which improves the service life of the furnace door guide groove;

The utility model has the advantages of simple structure, easy manufacturing, low manufacturing cost and high economic benefit.
