Embodiment Construction

[0036] An example of the specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0037] According to the logistics control method of twin continuous casting machines with single roller table and double heating furnaces of the present invention, when casting machines A and B are respectively supplying two heating furnaces of A and B, furnace loading is selected preferentially, and the time of feeding can be compared and the time of furnace loading can be compared. Comparing and pumping steel moment calculations,

[0038] Suppose: u is the uth slab of the current block of A casting machine, v is the vth slab of the current block of B casting machine,

[0039] T a is the casting time of u slab; Ta = la na , l a is the slab length of line A (10.8~15.6m), n a is the casting speed of line a (2~3.3m / min),

[0040] T b Casting time for v...

Abstract

The present invention provides a material flow control method for continuous casting and continuous rolling workshop, and is applicable to equipment arrangement mode in which two continuous casting machines are set and their output roller conveyers are combined together, then fed into one heating furnace, and its control method mainly adopts four time comparison: precedence charging time comparison, selecting A casting machine U slab or B casting machine V slab, which can be precedently charged; feeding time comparison of V slab; chargint time comparison of V slab and stripping time comparison after heating. Said invention can implement continuous casting-heating furnace-rolling line semi-rigid connection, and can raise their production capacity.

Description

technical field [0001] The invention belongs to the field of continuous casting and rolling of steel plates, in particular to a logistics control method in a single roller table double heating furnace system of a double continuous casting machine. Background technique [0002] In the continuous casting and rolling workshop, due to various reasons, it is possible to build two slab (or medium-thin slab) continuous casting machines, and the output roller tables of the two continuous casting machines must be merged together and then lead to the two slabs with a single roller table. A heating furnace, from two streams merged into one stream, a logistics conflict will occur on the roller table between the confluence and the first heating furnace after the confluence. If the logistics is out of order and not optimized, it will cause mutual restriction of two four-strand continuous casting machines, two heating furnaces and rolling lines, which will further cause logistics chaos, or...
