In the Continuous Casting Process, How to Accurately Control the Temperature of Molten Steel?
by Luoyang Judian Professional Steel Casting and Rolling Equipment MIn the continuous casting process, the temperature of molten steel
has a great influence on the entire production line. Therefore, we must
strictly and accurately control the temperature of molten steel to ensure
normal production. So, how to accurately control the temperature of molten
steel? Today, Luoyang Judian introduces several methods for your reference.
1. Establish a converter heat balance system
The heat balance in the furnace is the basis for the stable
production of the converter, and it is also the prerequisite for the stable and
smooth operation of the subsequent process. If the heat balance in the furnace
cannot be guaranteed, low-temperature molten steel will easily occur when the
heat is insufficient.
2. Do a good job in furnace-type Control
A reasonable furnace type is not only a necessary condition for the
normal production of the converter but also an important means to promote the
progress of economic and technical indicators. When the furnace type is not
good, the agitation of the liquid medium in the molten pool cannot meet the
requirements, which will produce a series of adverse effects.
The key parameters of furnace type control include furnace bottom
height, liquid level height, furnace mouth diameter, furnace wall thickness,
furnace bottom thickness, furnace shape, etc. Only when the furnace type is
normal can the process be stable and the metallurgical effect of the converter
can be fully exerted.
3. Ladle cover
Whole-process capping refers to the automatic capping and uncovering
of the ladle during the circulation of each process. It ensures that the ladle
is always covered in each link, reducing heat loss at the mouth of the ladle.
Its thermal insulation effect is remarkable, which can effectively reduce the
temperature drop in the process, and is the key to realizing the low
temperature, constant speed, and fast casting technology of high-efficiency
continuous casting machines. The whole-process capping technology realizes
molten steel casting with low superheat, ensures stable billet quality, and
reduces the accident rate of continuous casting machines.
4. Improve ladle and Tundish Masonry Process
During the production cycle of a furnace of steel, the storage time
of molten steel in the ladle is as long as 30 minutes or more. The heat loss of
molten steel in the ladle is mainly the heat loss of the mouth of the ladle and
the heat dissipation of the ladle wall. The mouth of the bag can be added with
an insulating agent or covered to reduce heat loss. By improving the ladle
masonry process and adding thermal insulation fiber or thermal insulation felt
to the ladle refractory layer, the temperature drop of the ladle wall can be
effectively reduced.
5. Strengthen the Control of Process Details
In steelmaking production, molten steel goes through many processes,
and any small link out of control will cause the temperature control system to
fail. First of all, it is necessary to strengthen the maintenance of the
tapping hole. The molten steel is discharged from the converter into the ladle,
and the shape, size, tapping time of the tapping hole, and the shape of the
steel flow have a great influence on the temperature drop of the tapping.
The above are several methods for accurately controlling the
temperature of molten steel introduced by Luoyang Judian. Hope these methods
can help you.
