どの添加剤は、水和して、硬化剤としての作用が
失われる場合がある。(Conventional Technology/Problems) For the lining of industrial kilns, instead of the conventional brickwork, monolithic refractories are increasingly being used for labor-saving and economical reasons. However, when monolithic refractories are packaged in bags and a number of days pass after shipping, the pot life (fluidity retention time after mixing with water) and curing time change during construction, reducing construction efficiency. do. This is because additives such as binders and peptizers cause changes in the monolithic refractories over time due to moisture absorption due to their deliquescent properties and reactions between additives. Additionally, additives such as cement and magnesia powder may become hydrated and lose their effect as hardeners.

あつた。 As a countermeasure to this problem, it may be possible to introduce additives into the mixer during the mixing with water during mixing before construction. However, in order not to reduce the operating rate of the furnace, the mixing and construction had to be done quickly, and there was a risk of forgetting to add additives or adding the wrong amount. Moreover, if the amount and types of additives to be added are large, it is troublesome for the operator.

緒にミキサー内に入れても何んら支障がないこと
を知り、本考案を完成するに至つたものである。(Means for solving the problem) In order to solve this problem, the present inventors first considered including a pouch containing a predetermined amount of additive in each package of monolithic refractories. Ta. This method eliminated the problem of forgetting to add additives or making mistakes in the amount of additives added, but new drawbacks occurred, such as the hassle of opening the sachets and the ease with which the sachets got mixed into the monolithic refractories. After further consideration, we found that by making the material of the sachet containing the additives water-soluble, there would be no problem in adding it to the mixer together with the monolithic refractories without opening the bag during water-mixing. Knowing this, we completed the present invention.
本考案は、不定形耐火物を入れた袋の中に、水
溶性シートで包んだ添加剤を内在させたことを特
徴とする、不定形耐火物梱包体である。 The present invention is a monolithic refractory package characterized in that an additive wrapped in a water-soluble sheet is contained in a bag containing the monolithic refractory.
（実施例） 以下、図面にもとづいて本考案実施例を示す。(Example) Embodiments of the present invention will be described below based on the drawings.

トからなる。不定形耐火物１は耐火材料粉末が主
体である。 The figure shows a vertical sectional view of a package in which a monolithic refractory 1 is placed in a bag 2. The material of the bag 2 is paper, synthetic resin sheet, etc. Kraft paper is generally used for bags containing 10 to 40 kg, and bags containing 150 to 1000 kg
Large-sized container bags, which are large enough to accommodate containers, are generally made of sheets made of polypropylene, rubber, or the like. The monolithic refractory 1 is mainly composed of refractory material powder.
本考案では、この袋２の中に水溶性シート４で

は、不定形耐火物の施工において不可欠な、例え

塩、ケイ酸塩、炭酸塩などの結合剤、解こう剤な
どである。 In the present invention, the bag 2 contains an additive 3 wrapped in a water-soluble sheet 4. Specific examples of the additive 3 include binders such as cement, agnesia powder, phosphates, borates, silicates, and carbonates, deflocculants, etc., which are essential in the construction of monolithic refractories.
添加剤３の種類が複数で、それらが互いに反応
し合う場合は、複数の水溶性シートに包み分けて
もよい。潮解性の比較的大きいものを包み、そう

い。また、添加剤３の量が多い場合も、複数の包
み分けてもよい。 If there are multiple types of additives 3 and they react with each other, they may be wrapped in multiple water-soluble sheets. Those with relatively high deliquescent properties may be wrapped, and those that are not deliquescent may be mixed in the monolithic refractory. Also, when the amount of additive 3 is large, it may be divided into multiple packages.
水溶性シート４の具体的材質は、ポリビニール

つ迅速である。 Specific materials for the water-soluble sheet 4 include polyvinyl alcohol (PVA), methyl cellulose, carboxymethyl cellulose, water-soluble paper, and the like. In addition, any water-soluble material with a certain degree of strength can be used. The thickness is preferably 10 to 100μ. Various ways of wrapping can be considered. It may be simply folded and wrapped, but it is easier and faster to form the sheet into a bag shape in advance, add additive 3 to it, and seal the opening with a water-soluble adhesive or hot pressure bonding. .

シート４が破れるなどの心配もない。 In the bag 2 containing the monolithic refractory 1, the location where the binder 3 wrapped in the water-soluble sheet 4 is contained is not particularly limited, but it is preferably above the monolithic refractory 1. This is because when the bag 2 is opened, it is easy to confirm that the water-soluble sheet 4 is contained. Further, there is no fear that the water-soluble sheet 4 will be torn due to the weight of the monolithic refractory 1.

まつたくない。(Function) The monolithic refractory package configured as described above does not change over time because the additives are isolated by the water-soluble sheet 4, and the workability of the monolithic refractory can be stabilized. When water is added and kneaded before construction, the water-soluble sheet 4 is dissolved by the action of added water (usually 4 to 10 wt% applied externally to the monolithic refractory) and the additive 3 is dispersed, so that the water-soluble The sheet 4 is placed in the monolithic refractory 1 without taking any steps such as opening the package.
It can also be thrown into a mixer. Since the sheet 4 is water-soluble, even if it mixes into the monolithic refractory 1, it will not cause any harmful effects such as forming voids in the construction body.

のを防止し、より均一な施工体が得られる。 The specific material of the water-soluble sheet 4 is not limited in any way as shown above, but if it is made of polyvinyl alcohol, it will act as a thickener after being dissolved, and it will act as a fine powder refractory material in the monolithic refractory. This prevents the particles from lifting up, resulting in a more uniform construction.

After 6 months had passed, this monolithic refractory package was opened, mixed with 6 wt% of added water, and then poured into a pot. There was no noticeable change in pot life or curing time due to aging, and the results were very good. The workability was demonstrated. In addition, at this time, without opening the additive wrapped in a water-soluble sheet,
The sheet was put into a mixer together with the monolithic refractory, but the sheet immediately melted.
