The invention relates to a melting apparatus (100) for melting paraffin (1), having: a melting container (110) for receiving paraffin (1) to be melted; a storage container (190) for storing molten paraffin (4); having a melting container heating device (120) for heating the melting container (110), having a storage container heating device (191) for heating the storage container (190), having a fluid connection (113) fluidically connecting the melting container (110) and the storage container; the melting container (110), the storage container (190), and the fluid connection (113) being arranged so that molten paraffin (4) flows out of the melting container (110) into the storage container (190).

Methods and systems for managing a heating process are disclosed. An example method can comprise removing a first portion of a material from a vessel and measuring a first parameter of a second portion of the material in the vessel. The second portion of the material can remain in the vessel after the removal of the first portion. The method can comprise, determining a volume of the second portion of the material based on the first parameter, updating a second parameter based on the volume, and performing a process based on the updated second parameter.

A refill system includes a tempering furnace, a refill furnace which stores the molten potassium nitrate obtained by melting powdered potassium nitrate, a supply unit which supplies the molten potassium nitrate to the tempering furnace, a tempering furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the tempering furnace, a refill furnace side load measuring unit which measures a load amount of the molten potassium nitrate in the refill furnace, and a central control unit which checks the load amount of the molten potassium nitrate in the tempering furnace and the refill furnace in real time, and controls the supply unit to stop supplying the molten potassium nitrate to the tempering furnace when the load amount of the molten potassium nitrate in the tempering furnace is greater than or equal to a predetermined load amount.

The invention relates to a device and to a method for sensing a conveying rate at which liquid material is filled into a metallurgical target vessel (6) from a pivotable starting vessel (4). For this purpose, means for determining an amount of liquid material with which the initial vessel (4) has been filled and means for sensing an amount of the liquid material which is discharged toward the target vessel (6) or filled into the target vessel (6) by pivoting of the starting vessel (4) are provided.

A system and equipment to measure and control the feeding of load material into an electrical arc furnace (EAF) includes an automatic control device feeding the load material; a measuring device positioned between the EAF and the tilting platform that includes an upper plate adapted to slide against the EAF, a lower plate engaged to the tilting platform, and a ring structure therebetween having a peripheral ring wall, a ring plate extending across the ring structure, and a contact member coupled to the ring plate that upperly contacts the upper plate and lowerly approaches, without contacting the lower plate; and one or more sensors measuring a deformation of the ring plate upon application of a load on the upper plate.
