Description
Technical Field
The utility model relates to a heating furnace tapping roller way basis protection device belongs to roller way basis technical field.
Background
The heating furnace discharging roller bed foundation is formed by pouring reinforced concrete, and the roller bed frame stretches across the two roller bed foundations. When the produced blank is square blank with 390mm × 510mm × 6800mm and round blank with diameter 600mm × 5000mm, the weight of the blank is more than 10 tons. Because the roller bed foundation is close to the door of the heating furnace, when the furnace door is opened, the heat radiation is large (the temperature of the furnace door is 1250 ℃, so that the concrete is cracked, the reinforcing steel bars are softened, the impact force of the billet on the roller bed foundation is large when the billet walks on the roller bed, the roller bed foundation close to the furnace door is collapsed, and the foundation bolts are broken; the elevation deviation of the roller way is large, and the billet cannot normally run. When the elevation of the roller way is readjusted after the roller way foundation is cracked, the roller way frame cannot be fixed on the roller way foundation, the adjusting time is long, the adjusting effect is poor, and the production efficiency is affected.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a heating furnace tapping roller way basis protection device is provided to above-mentioned prior art, guarantees that the roller way basis is firm reliable, improves production efficiency.
The utility model provides a technical scheme that above-mentioned problem adopted does: a heating furnace discharging roller way base protection device comprises a roller way frame and a roller way base frame, wherein a water cooling box seat is arranged between the roller way frame and the roller way base frame, the water cooling box seat is fixed on the roller way base frame, and the roller way frame is fixedly connected with the roller way base frame;
be equipped with the cooling water passageway in the water-cooling tank seat, set up water inlet and delivery port on the water-cooling tank seat, water inlet and cooling water passageway one end intercommunication, delivery port and the cooling water passageway other end intercommunication, cooling water flows to the cooling water passageway through the water inlet, cools off roller way foundation frame, and the cooling water after the heat exchange flows through the delivery port.
The cooling water passage is provided in a serpentine shape.
The water cooling box seat is an L-shaped piece.
Compared with the prior art, the utility model has the advantages of: a heating furnace discharging roller way foundation protection device is characterized in that an L-shaped water cooling box seat is arranged between a roller way frame and a roller way foundation frame, so that the roller way foundation frame is wrapped by the L-shaped water cooling box seat close to a billet. The water cooling box base can not only resist thermal radiation and cool the roller way foundation, but also increase the stress area of the roller way foundation, reduce the impact force of the billet on the roller way foundation, avoid the collapse of the roller way foundation, avoid the readjustment and improve the production efficiency.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the protection device for the furnace outlet roller bed foundation of the heating furnace in the embodiment includes a roller bed frame 6 and a roller bed foundation frame 3, wherein the roller bed foundation frame 3 is obtained by knocking out original cracked concrete. An L-shaped water cooling tank seat 1 is arranged between the roller way frame 6 and the roller way base frame 3, the L-shaped water cooling tank seat 1 and the roller way base frame 3 are fixed through a fixing bolt 2, the L-shaped water cooling tank seat and the roller way base frame are welded firmly through welding, grouting is carried out in the roller way base frame 3 through refractory castable, and a roller way base with the water cooling tank seat 1 is formed. The roller bed frame 6 is fixedly connected with the roller bed foundation through foundation bolts 4.
As shown in fig. 2, 3 and 4, a serpentine cooling water channel is arranged in the water cooling tank seat 1, a water inlet 5 and a water outlet 7 are formed in the water cooling tank seat 1, and the water inlet 5 and the water outlet 7 are arranged on the same plane. The water inlet 5 is communicated with one end of the cooling water channel, the water outlet 7 is communicated with the other end of the cooling water channel, the water inlet 5 is connected with cooling water through a metal hose, the cooling water flows to the cooling water channel through the water inlet 5 to cool the roller foundation frame 3, the cooling water after heat exchange flows out through the water outlet 7, the water outlet 7 is connected with the metal hose, and the cooling water after heat exchange is led into the slag flushing ditch.
An L-shaped water cooling tank seat 1 is arranged between the roller way frame 6 and the roller way base frame 3, so that the roller way base frame 3 is wrapped by the L-shaped water cooling tank seat 1 close to a steel billet. The water cooling box base 1 can not only resist thermal radiation and cool the roller way foundation, but also increase the stress area of the roller way foundation, reduce the impact force of steel billets on the roller way foundation, avoid the roller way foundation from collapsing, avoid readjustment and improve the production efficiency.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
