Description

Печи дл  отжига изделий, выполненные в виде вертикально или наклонно установленной шахты, условно разделенной на зоны нагрева (кристаллизации), отжига и охлаждени , известны.Furnaces for annealing products, made in the form of a vertically or obliquely installed shaft, conventionally divided into zones of heating (crystallization), annealing and cooling, are known.

Предлагаема  печь отличаетс  от известных тем, что в стволе шахты, ниже зоны отжига, устраиваютс  боковые отверсти  дл  отвода отход ш,их газов и отбора тепла от изделий.The proposed furnace differs from the known ones in that in the shaft of the shaft, below the annealing zone, side holes are arranged to divert waste, their gases and heat from the products.

Така  печь обеспеспечивает заданный температурный режим, требуемый дл  отжига изделий.Such a furnace provides the predetermined temperature conditions required for annealing the products.

На фиг. I показан продольный разрез описываемой печи; на фиг. 2 - разрез по А-А на фиг. 1; на фиг. 3 - разрез по Б-Б на фиг. 1.FIG. I shows a longitudinal section of the furnace described; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

Печь выполнена в виде шахтного ствола и состоит из двух основных частей: высокотемпературной нагревательной камеры /, имеющей посадочное отверстие 2 дл  изделий, и камеры отжига 3, котора  по существу  вл етс  продолжением нагревательной камеры.The furnace is made in the form of a shaft shaft and consists of two main parts: a high-temperature heating chamber / having a fitting hole 2 for products, and an annealing chamber 3, which is essentially an extension of the heating chamber.

В зависимости от условий камера отжига 3 может располагатьс  по вертикали или под углом естественного откоса обжигаемого материала (фиг. 1).Depending on the conditions, the annealing chamber 3 may be located vertically or at an angle of repose of the calcined material (Fig. 1).

Сжигание коксового, природного газа или жидкого топлива производитс  в нагревательной камере LCoke oven, natural gas or liquid fuel is burned in the heating chamber L

Движение продуктов горени  происходит сверху вниз и отвод их осуществл етс  при помощи дымососа через боковое отверстие 4.The movement of the combustion products occurs from top to bottom and they are discharged by means of an exhaust fan through the side opening 4.

Дл  отвода отход щих газов и отбора тепла от изделий устраиваютс  отверсти  5, 6, 7.For removal of exhaust gases and heat from the products, holes 5, 6, 7 are arranged.

Обычно в практике термообработки изделий из каменного .лить  примен ютс  две печи: одна дл  кристаллизации, друга  дл  отжига изделий.Usually, in the practice of heat treatment of stone products, two furnaces are used: one for crystallization, the other for annealing products.

В предложенной конструкции печи процессы кристаллизации и отжига осуществл ютс  в одной установке.In the proposed furnace design, the crystallization and annealing processes are carried out in one installation.

Дл  отжига изделий обычно примен ютс  горизонтальные печи «Лер с конвейерной сеткой и приводным устройством.For annealing products, horizontal Lehr furnaces with a conveyor net and a driving device are usually used.
