example in a pusher type reheating furnace billets are moved along the furnace through the action of pushers Billets can enter the furnace at different temperatures In the case study that will be
In the past few decades several numerical models have been developed for different types of reheating furnaces using different types of fuel [1][2][3][4][5][6] [7] [8][9][10][11][12][13][14][15
The slab reheating process for iron rolling to the small diameter wire in Ratchasima Steel Products Co Ltd factory Nakron Ratchasima Thailand use the reheating furnace walking hearth type
The results indicate that a capacity increase of approximately 14% is possible for pusher type reheating furnaces when additional electric heaters in the hearth are employed View
A coal fired pusher type reheating furnace is simulated with the help of an efficient numerical model The authors have improved over a numerical model developed in previous work to save more than
geometry of the furnace Types of Continuous Reheating Furnace Continuous reheating furnaces are primarily categorised by the method by which stock is transported through the furnace There are two basic methods · Stock is butted together to form a stream of material that is pushed through the furnace Such furnaces are called pusher type
For this the slabs are normally heated in gas or oi l red pusher type reheating furnaces In order to illustrate this a schematic setup of the furnace which is considered in the following is shown in Figure 1 Depending on the location of the burners the loc al temperature range and the dwell of the
Matura [2] replaces the reheating furnace burner to the type of regenerative burners combined with recuperator to get 80% efficiency Reheating furnace with an efficiency of less than 50%
The considered furnace is a pusher type reheating furnace that may contain up to 138 billets m b = 138 billets the billets enter the furnace one or two at a time from the left side; pushers trigger the billet movement from the entrance to the exit of the furnace The billet furnace inlet temperature can be very different in the range 0
The enormous potential of model based control and optimization for steel reheating furnaces is described in [11] where one of the proposed control approaches is based on a transient nonlinear
In this paper an Advanced Process Control system aimed at controlling and optimizing a pusher type reheating furnace located in an Italian steel plant is proposed The designed controller replaced
Pusher type heating furnace has many types 1 Depending on the fuel there are coal fired oil fired and gas fired continuous heating furnaces; 2 depending on the temperature system and furnace type there are two stage three stage intensified heating parallel flow and reverse heating continuous heating furnaces; 3 depending on whether there
Three dimensional of the turbulent reactive flow and radiative heat transfer problem in a walking beam type slab reheating furnace simulations are successfully performed in the present study by
The reheating process represents a key phase in the steel industry production chain raw materials derived from a continuous casting need to be suitably reheated in order to satisfy the specifications for the desired rolling procedure [] In the last years reheating furnace control and optimization has attracted the attention of process engineers and researchers due
To investigate the flow field temperature distribution and slab heating behavior in the furnace numerical modeling has become a crucial research method [1] [2] [3] [4] Han et al [5] presented a numerical study considering radiative heat transfer among the slabs and furnace walls to forecast the thermal efficiency of a reheating furnace Singh et al [6] performed a
This simple mechanical system ensures the billets slabs blooms and beam blanks moving through the furnace are always well aligned This together with the near total lack of cooled elements inside the heating chamber makes it highly energy efficient and gives you very low operating costs It also requires the lowest CAPEX of any type of furnace
