In order to
improve the absolute productivity of the furnace, it is necessary to improve
the unit productivity of the furnace. The higher the effective bottom strength
is, the higher the hourly output of the furnace is. To a certain extent, it
shows that the furnace has better thermal efficiency, higher heating efficiency
of bright annealed stainless steel tubes
and higher production operation level. In addition, attention should be paid to
improving the utilization coefficient of furnace bottom.
bottom utilization coefficient refers to the ratio of the effective bottom area
to the whole bottom area. The higher the utilization coefficient of the bottom
is, the larger the effective bottom area is. It will be conducive to increasing
the loading capacity and the hourly output of the furnace.
In the workshop,
the heating capacity of the bright
annealing stainless steel tube furnace should be determined according to
the hourly output, operation rate and annual product plan of the rolling mill.
The ability of the bright annealing
stainless steel tube
furnace must ensure that the rolling mill completes
the annual production plan within the specified operating time.
capacity of bright annealed stainless
heating furnace is the total quantity ofbright annealed stainless steeltube heated well in unit time,
expressed in tonnage, hour or tonnage/shift. In order to compare the thermal
working conditions of different furnaces, the unit productivity, i.e. the
bottom strength (kg/m 2.h), is often used to express it.
The effective bottom strength of P-type
medium-sized furnace is per kilogram/meter 2.hour. For example, the effective
bottom strength of inclined bottom furnace of small seamless stainless steel
pipe production unit is about 300-400 kilograms/meter 2.
G - The absolute
productivity of the furnace is the hourly output of the furnace, ton/hour.
hearth area，meter 2, There are many factors restricting the efficiencies
of vacuum annealing at present. The production technology of vacuum annealing
furnace on the market is not very mature and the production efficiency is
relatively low, which leads to high production cost of bright annealing
stainless steel tubes. How to improve the production efficiency ofbright annealing furnaceis the focus
